SpillPass for Raspberry Pi   v1.6

-A Simple Homebrew Plug and Play 3DS HomePass Relay and Fake “Nintendo Zone” Hotspot-



-Update-  With Nintendo’s recent change to their relay network, the SpillPass Pi now offers 12 streetpasses about every 8 – 10 minutes. That is enough streetpassing to keep you playing all the Mii Plaza games in rotation forever without breaks (with the current MAC list and timing structure, this device will never overlap into the 8-hour cool-down period)    🙂



SpillPass Pi aims to be a plug and play StreetPass relay and Nintendo Zone Hotspot that will function behind any standard home router without configuration.  Just plug it in and let it run! It runs on the Raspberry Pi hardware and runs the latest (as of this writing) version of Raspbian OS. Thanks goes out to the Raspberry Pi foundation as well as the HomePass community for their work and continued support and progress in helping people the world over complete these damned 3D Puzzles.


(Beta Testing)




Step 1. Buy the components

This project requires….

A Raspberry Pi Model B    (512 MB / Revision 2)   *Note: revision matters.  NOT a B+ model (they work but require changes to the networking config on the image)
A quality micro USB power supply that can provide 1A @ 5V  (a decent one as to avoid brown-outs since it is powering a wifi chip)
An 8GB SD card (and a USB SD Card reader for your PC if you don’t already have one)
A USB Adapter compatible in Monitor Mode and running a chipset that works with the nl80211 driver (link below – I recommend the BELKIN 150N  (F6D4050)) or other RT3070 chipset low draw adapter.
A free port on your router/switch
Raspberry Pi Case (optional but makes it look nice)
HDMI cable (optional to hook the device to a monitor)

Decently priced kits (they lowered their kit prices significantly) with good power supplies and cases for the Pi itself are sold by CanaKit
The cheapest USB Wifi Adapter with the required chipset comes in at just under $10  (F6D4050)

All of these items I have listed on, and can be bought directly through the hardware page. There are a few of the best/cheapest options for each piece.

I don’t run advertising on this site, and I don’t accept donations. All I ask if that if you are going to purchase this hardware via amazon anyway, that you consider buying it through my site. It costs exactly the same to you, and any proceeds I receive will go towards hosting this site. If proceeds ever go above my hosting costs, I will donate these back to the Raspberry Pi foundation charity.

*Update* I am very sorry to have to take the comments section of this website down, but there were too many people posting not just links to kits to help others, but their own amazon referral links to steal the few dollars a month this site makes to keep itself running. That is not cool.  🙁   As always, I am usually idling in #3DS on Efnet if people need assistance buying or putting together their unit. Sorry for the inconvenience, but a few greedy people spoil it for everyone.



Step 2. Download the required software

Latest SpillPassPi image located here:       Mirror 1    |    Mirror 2   |   Torrent

SD Card Imaging Software (Win32 Disk Imager) from here:     http://sourceforge.net/projects/win32diskimager/
ColaSoft Mac Scanner Free (Optional if you want to find the device IP after a reboot without a monitor attached):  http://www.colasoft.com/mac_scanner/index.php?act=mac_scanner
Putty (Optional if you would like to SSH into the terminal of the device):  http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
WinSCP (Optional if you would like to transfer files back and forth to the device):  http://winscp.net/eng/download.php


Step 3. Flash the SpillPassPi image to the SD card

Insert the USB SD card reader into your PC.
Insert the SD Card into the card reader.
Run Win32 Disk Imager and ensure that your SD Card is now showing and selected under the “Device” dropdown box on the right hand side.
Unzip the SpillPassPi image file you downloaded earlier.  (windows can do this for you if you right click the file and select extract)
Select the SpillPassPi image in the Image File area.
Click on WRITE.  –  It will notify you when it is completed.

*Note – Some people have had issues with the bootup after imaging. If this happens to you, you can either use dd to image the card if you are a linux person, or just make sure to format the SD card first with the official SD Formatter software located here – https://www.sdcard.org/downloads/formatter_4/eula_windows/
You should not encounter this issue if you buy your SD card with the CanaKit (though it isn’t much of a problem)


Step 4. Fit them together

Fit the Pi into your case if you have one, and insert the now loaded SD card into the proper slot.
Plug the Wifi USB Adapter into the top USB slot, a network wire directly from your router or switch into the on-board Ethernet, and the SD card into the SD slot.
Plug in a monitor and keyboard if you like (optional).

Step 5. Power it up

Plug in the MicroSD USB Power chord.
The SpillPassPi will power up!

Step 6. Enjoy streetpassing and connecting to Nintendo Zone from the comfort of your own home

You are all set. Enjoy your new SpillPass Pi box!



Because the device is in rotation mode, there is a brief drop and pickup in WiFi service that some games cannot handle. It is recommended that you connect to your normal WiFi while you play these games online. I may add an option to disable/enable Mac Rotation from the WebGUI at a later time to assist with this.

Additional Advanced Notes

This device pulls an IP via your routers DHCP setting and fully releases it upon reset. It is very likely that the IP may change upon each reboot. There are two decent options to handle this.
If you have it plugged into a monitor, the system launches a new connected screen session on load (to separate the MAC rotation and hostapd script into it’s own process). This screen lists off the IP address on each refresh. You can use this to connect via SCP, Putty, or to the WebGUI via http://IPADDRESSOFUNIT (currently offers only a clean reset and shutdown option).
Another easy method to retrieving the IP of the device is by looking up the mac address. By running ColaSoft Mac Scanner Free, and selecting SCAN with the default settings (it is initialy set to scan your local subnet), you can retrieve all the mac addresses of the active devices on your network. Since we are specifically rotating through a specific range of mac addresses by default, it is easy to spot.  By default, the mac should be prefixed with  4E:53:50:4F:4F:XX

Additionally, you may modify the MAC Address list used by simply changing the file located at /etc/hostapd/mac_nintendozone

Mac Finder


Additional Security Notes

This device does indeed open up a non-password encrypted wifi session. It is designed to be as simple as possible, as compatible as possible (to work behind any normal home router,) and to provide Nintendo Zone Access (does not work properly if WPA is enabled.)
It’s range however is fairly short as it is using very little transmit power. It should not be a major concern for a small house. If however you are in a densely packed area and are security oriented, WPA may be enabled and configured by editing the mac changer script located in /etc/hostapd    There is a section of this script that generates the new host config on each rotation.  A Mac Address filter (that you would add your 3DS mac too) can also be created to maintain Nintendo Zone Compatibility while locking down the hotspot without WPA. These processes may be covered in a later update.
SSH is also enabled for the root user. You may change this password if you wish without issue to the functionality of the script. WebGUI access is via htaccess file. Change accordingly if required.




Change log:

Version 0.1  –  Success! Found the cheapest and most readily available wifi chipset that supports what we need to do.  Let the testing begin.

Version 0.5 – First successful streetpass via a single statically assigned mac. Working off router’s DHCP without opening any ports.

Version 0.6 – Tinkering with Semperverus’s rotational script. Modified, but used as primary learning source. Ty Semperverus.

Version 0.8 – First successful rotating streetpass.

Version 1.0 – First fully automated streetpass rotation from boot. Setup hostapd session in a named screen that takes over the primary monitor session on load. Displays IP and information.

Version 1.1 – Began very simple WebGUI interface.

Version 1.2 – Minor tweaks for faster boot and stability.

Version 1.3 – Just because.

Version 1.313 – Reboot and Shutdown implemented in webGUI

Version 1.5 – First Release

Version 1.6 – Added some auto-recovery if things go wrong internally. Rotation speed has also been shortened and better staggered.
